Revert "ADD: “handling nulls” for fighter and sorcerer (instead of actually handling nulls, I’m instead just creating a dummy Fighter and Sorcerer object, that is not in the game, but that can be used before we finally .Find it in the game). This seems to work, the game runs and a Fighter gets created upon connection to the server. issue #73"

This reverts commit 86e32bffd3f8f5fe418dcdb668970f0787dfa850.
